Twenty-four-year-old Katherine Gonzalez pleaded guilty in August to having an inappropriate relationship with the boy.

She told police the reason for her actions, among others, was her claim that her victim was “chronically depressed” and she wanted to make him “happy,” according to Yahoo News.

Gonzalez befriended the boy while he was a student at Atlas Preparatory Academy, which on its website claims to “provide an educational program which engages our students in learning experiences that meet their academic, social and emotional needs.” When not in school together, the victim and Gonzalez began communicating via Snapchat and Instagram.

The boy later told police, on February 25, she picked him up in her car and they kissed, and she had had the boy touch her genital area over her clothes. They later went to Gonzalez's apartment, where they watched the movie "Deadpool," again kissed, and she rubbed her hand over the boy's groin and had him touch her breasts over her clothing, according to the Milwaukee Journal-Sentinel.

Police learned of the sexual contact after the boy’s mother noticed his phone buzzing at 3:30 am on a Monday night. She took the phone away from the boy and discovered text messages from Gonzalez describing their encounters, including references to being touched “down there.” She alerted police, who later interviewed the victim.

After being arrested and questioned by police, Gonzalez gave a slew of reasons for the crime. She claimed she was nervous that her adult boyfriend was about to propose marriage to her, she said she wanted to make the boy happy to bring him out of his depression and she claimed to be the victim of a sexual assault herself in college.

In August, Gonzalez pleaded guilty to second-degree sexual assault of a child. At her sentencing Thursday, she said she had been getting treatment since her release on bail last March and tearfully apologized for her “unthinkable actions” to the boy and his family, even though they were not present in court.

Judge Mark Sanders called Gonzalez's behavior "predacious," and sentenced her to five years in prison with another seven years of extended supervision upon her release.
